SURFACE-WATER RECORDS

PERIOD OF RECORD - Discharge: August 1914 to June 1915 (twice-daily gage heights and corresponding discharge), July 1915 to current year. Water-quality records: Water years 1953, 1965-66, 1994.

GAGE - Data Collection Platform with satellite telemeter. Datum of gage is 379.48 ft above NAVD 1988, estimated from topographic map. Prior to May 13, 2020, datum reported as 388 ft above NAVD 1988, estimated from digital map. Prior to June 8, 2016, datum reported as 380 ft above NGVD 1929, estimated from topographic map. Prior to June 30, 1915, non-recording gage, June 30, 1915, to Sept. 20, 1938, water-stage recorder, and Sept. 21 to Dec. 31, 1938, non-recording gage, at site 2.2 mi upstream at different datum. Jan. 1 to Mar. 29, 1939, non-recording gage, and Mar. 30, 1939, to Sept. 12, 1941, water-stage recorder, at site 0.4 mi downstream at different datum.

COOPERATION - Massachusetts Department of Conservation and Recreation, Office of Water Resources.

REMARKS - Flow regulated by power plants and by Lake Monomonac and other reservoirs; high flow regulated by Birch Hill Reservoir 22 mi upstream since 1941 and Tully Lake since 1948. Greater regulation by power plants prior to 1966.

WY2016: Records good, except for periods of ice effect, Jan. 6-9, 13-29, Feb. 10-11, and 13-16, which are poor.

WY2015: Records fair due to doubtful stage-discharge relation, except for periods of ice effect, Dec. 30 to Jan. 3, Jan. 9-20, and Jan. 22 to Mar. 25, which are poor.

WY2014: Records fair except those for estimated daily discharge, which are poor.

The maximum historical peak flow of 29,000 cfs on Sept. 22, 1938 is based on a rating extended above 19,700 cfs on the basis of the mean discharge of two slope-area measurements. The maximum peak stage of 13.37 ft is from flood marks, at site and datum then in use.

WATER-QUALITY RECORDS
